Application July 19, 1937, Serial No. 154,390

2 Claims. (Cl. 120111) The object of this invention is to provide a pen of special form that is adapted for the purpose.

of making letters that would be used principally for advertising purposes, but for other purposes as well.

Another object of the invention is to provide a pen by which shaded letters can be made either in script or in printed letters.

Another object of the invention is to provide a pen that will ,normally carry a considerable quantity of ink, so that a considerable number of letters can be printed or written therewith with a single filling or dipping of the pen.

Another object of the invention is to make a pen that can be made in one piece bent out of one blank.

These and other objects of the invention will be illustrated in the drawing, described in the specification, and pointed out in the claims at the end thereof.

In the drawing:

Figure 1 is a view of the pen looking at it from the bottom side thereof.

Figure 2 is a side elevation of the pen.

Figure 3 is a plan view of the blank from which the pen is made.

In the drawing like reference numerals indicate like parts.

Pens embodying my invention may be made of thin sheet metal such as copper, brass, or of other materials such as Celluloid.

The pen shown in Figures 1 and 2 is formed from the blank shown in Figure 3. This pen is made by bending the right hand side of the blank I shown in Figure 3 along the dotted line 2 shown in Figure 3, the metal being bent with a sharp bend so that the two sides are brought closely together as indicated at 3 and 4 in Figure 1. The left hand side of the blank shown in Figure 3 is bent to a curve having a radius of about a half inch or more, forming the segment of a cylinder, the curvature of which segment corresponds to the curvature of the socket that is provided in the pen holder for receiving the base of the pen. This curved cylindrical part of the pen is indicated in Figure l by reference numeral 1.

The parts 3 and 4 constitute the points of the pen and because they are brought close together they will hold ink by capillary attraction when 6 dipped into a bottle of ink, and the flared portion or open space indicated between 5 and 6 will form a reservoir that will hold one or more drops of ink from which the ink will feed forward to the points.

As shown in Figure 2, the top of the pen point is beveled as indicated at 8 and the end of it is made blunt as indicated at 9, and the bottom of the pen point has a square corner as indicated at l0; By bearing on the paper with the square corner the pen will make a narrow or fine line. By bearing on the paper with the blunt portion 9 the pen will make a broad line, or will make the horizontal bars of a letter with a heavy shading, or will make the corresponding portions of script letters thin or heavy as may be desired.

By bearing on the paper with the beveled portion 8 of the pen, the pen will make a fine line on the downstroke and will make a coarse line on the side stroke. penholder will be held with reference to the paper in the position most suitable to secure the desired result.

I claim:

1. A pen formed from a single blank, said pen having at its forward end two layers of metal placed close together at the point by folding on a central axial line, said layers being separated back of the point sufliciently to form a pocket for a small quantity of ink that will feed between the two layers.

2. A pen formed from a single blank, said pen having at is forward end. two layers of metal placed close together, said layers being separated back of the point sufficiently to form a pocket for a small quantity of ink that will feed between the two layers, the layers being beveled off at one side of the point and rounded off on the other side, the intermediate part of the point being left square.

CHARLES E. BLUHM.

In each case the pen and 25
